Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 15875-1 was prepared by the European Committee for Standardization (CEN) in collaboration with Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, Subcommittee SC 2, Plastics pipes and fittings for water supplies, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

Foreword This document (EN ISO 15875-1:2003) has been prepared by Technical Committee CEN/TC 155 Plastics piping systems and ducting systems, the secretariat of which is held by NEN, in collaboration with Technical Committee ISO/TC 138 "Plastics pipes, fittings and valves for the transport of fluids". NOTE This standard was submitted for CEN enquiry as pren 12318-1:1996. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2004, and conflicting national standards shall be withdrawn at the latest by December 2005. This standard is part of a System Standard for plastics piping systems of a particular material for a specified application. There are a number of such System Standards. System Standards are based on the results of the work undertaken in ISO/TC 138 "Plastics pipes, fittings and valves for the transport of fluids", which is a Technical Committee of the International Organization for Standardization (ISO). They are supported by separate standards on test methods to which references are made throughout the System Standard. The System Standards are consistent with general standards on functional requirements and recommended practices for installation. EN ISO 15875:2003 consists of the following Parts 1), under the general title Plastics piping systems for hot and cold water installations Crosslinked polyethylene (PE-X) Part 1: General (the present standard) Part 2: Pipes Part 3: Fittings Part 5: Fitness for purpose of the system Part 7: Guidance for the assessment of conformity (CEN ISO/TS 15875-7). This Part of EN ISO 15875 includes a Bibliography. At the date of publication of this standard, System Standards for piping systems of other plastics materials used for the same application are the following: EN ISO 15874, Plastics piping systems for hot and cold water installations Polypropylene (PP) (ISO 15874:2003) EN ISO 15876, Plastics piping systems for hot and cold water installations Polybutylene (PB) (ISO 15876:2003) EN ISO 15877, Plastics piping systems for hot and cold water installations Chlorinated poly(vinyl chloride) (PVC-C) (ISO 15877:2003) For pipes and fittings which have conformed to the relevant national standard before 1 st November 2003, as shown by the manufacturer or by a certification body, the national standard may continue to apply until 30 th November 2005 According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and the United Kingdom. 1) This System Standard does not incorporate a Part 4 Ancillary equipment or a Part 6 Guidance for installation. For ancillary equipment separate standards can apply. Guidance on installation of plastics piping systems made from different materials intended to be used for hot and cold water installations is given by ENV 12108:2001 [1].

Introduction The System Standard, of which this is Part 1, specifies the requirements for a piping system when made from crosslinked polyethylene (PE-X). The piping system is intended to be used for hot and cold water installations. In respect of potential adverse effects on the quality of water intended for human consumption, caused by the product covered by EN ISO 15875: This standard provides no information as to whether the product may be used without restriction in any of the Member States of the EU or EFTA; It should be noted that, while awaiting the adoption of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of this product remain in force. Requirements and test methods for components of the piping system are specified in Part 2 and Part 3 of EN ISO 15875:2003. Characteristics for fitness of purpose (mainly for joints) are covered in Part 5. Part 7 (CEN ISO/TS 15875-7) gives guidance for the assessment of conformity. This Part of EN ISO 15875 specifies the general aspects of the plastics piping system. vi ISO 2003 All rights reserved
1 Scope This Part of EN ISO 15875 specifies the general aspects of crosslinked polyethylene (PE-X) piping systems intended to be used for hot and cold water installations within buildings for the conveyance of water, whether or not intended for human consumption (domestic systems), and for heating systems, under design pressures and temperatures according to the class of application (see Table 1). This standard covers a range of service conditions (application classes) and design pressure and pipe dimension classes. For values of T D, T max and T mal in excess of those in Table 1, this standard does not apply. NOTE It is in the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes. It also specifies the test parameters for the test methods referred to in this standard. In conjunction with the other Parts of EN ISO 15875 (see Foreword) it is applicable to PE-X pipes, fittings, their joints and to joints with components of other plastics and non-plastics materials intended to be used for hot and cold water installations. 2 Normative references This Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this Standard only when incorporated in it by amendment or revision.
